The claim that some individuals see colored halos or auras around faces has long been part of popular folklore. Here we report on a 23-year-old man (subject TK) diagnosed with Asperger's disorder, who began to consistently experience colors around individuals at the age of 10. TK's colors are based on the individual's identity and emotional connotation. We interpret these experiences as a form of synesthesia, and confirm their authenticity through a target detection paradigm. Additionally, we investigate TK's claim that emotions evoke highly specific colors, allowing him, despite his Asperger's, to introspect on emotions and recognize them in others.
